Cistanche is a traditional Chinese medicinal herb that has gained attention for its potential anti-aging properties. While its use in Traditional Chinese Medicine (TCM) for enhancing vitality and longevity is well documented, recent scientific studies have begun to explore its effects on aging-related processes. Preclinical research, primarily in animal models and cell cultures, suggests that Cistanche extracts may exert anti-aging effects through antioxidative, anti-inflammatory, and neuroprotective mechanisms. Some studies have demonstrated that Cistanche polysaccharides can increase the activity of antioxidant enzymes (such as SOD and catalase), reduce oxidative stress markers, and improve mitochondrial function—factors implicated in the aging process. Additionally, certain compounds in Cistanche, like echinacoside, may help protect neurons and enhance cognitive function in animal models of aging.

However, human clinical evidence remains limited. A few small-scale trials have investigated Cistanche for fatigue and cognitive support in elderly populations, but these studies are not robust enough to definitively confirm anti-aging benefits. Most claims remain extrapolated from animal or in vitro research, and larger, well-designed human trials are needed. In summary, while Cistanche’s use for aging prevention is rooted in tradition and supported by promising but preliminary scientific findings, the overall quality of evidence is modest (rated 2 out of 5), warranting cautious optimism pending further research.
